Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of fire resistance testing devices, specifically relating to a fire resistance testing furnace. Background Technology
[0002] Fire resistance is a crucial performance characteristic of building components. Good fire resistance allows building components to maintain their structural function during a fire and confine the fire within a limited space, ensuring the building's fire safety. The fire resistance performance of building components can be obtained by performing a full-scale fire resistance limit test. During a full-scale fire resistance limit test, the sample to be tested (fire doors, fire windows, fire shutters, firewalls, etc.) must first be mounted on a dedicated fire resistance testing frame. This frame is then fixed to a fire resistance testing furnace before the fire resistance limit test is performed. Currently, there is a lack of a new type of fire resistance testing furnace that facilitates the fixing and detachment of the fire resistance testing frame. Utility Model Content

[0004] The present invention adopts the following technical solution: A refractory testing furnace includes a furnace body; the furnace body has a combustion chamber for containing a flame for combustion; the furnace body is provided with a flue pipe connected to the combustion chamber; the furnace body is directly or indirectly provided with a support member for facilitating the fixing or detachment of the refractory testing frame.
[0005] Furthermore, it also includes a first column; the first column is disposed on the side of the furnace body; the support member is disposed on the first column.
[0006] Furthermore, the support member is positioned at a distance of 50mm to 1500mm below the top of the furnace body.
[0007] Furthermore, the first column with the support member is provided on both the left and right sides of the furnace body.
[0008] Furthermore, the support member on the left and the support member on the right are arranged symmetrically.
[0009] Furthermore, the geometric center of the frontal section of the exhaust duct is 0.3m to 1.5m vertically from the ground.
[0010] Furthermore, the furnace body is equipped with several burners for generating flames.
[0011] Furthermore, the support member is an inclined support member that is tilted upwards.
[0012] Furthermore, the horizontal length of the inclined support member is 200mm to 500mm, the horizontal width is 30mm to 200mm, and the vertical section height is 30mm to 200mm.
[0013] Furthermore, the angle between the inclined support and the vertical surface is 30° to 85°.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model discloses a refractory testing furnace, in which support members are directly or indirectly provided on the furnace body. The support members facilitate the fixing or detachment of the refractory testing frame. When a refractory test is required, the refractory testing frame carrying the test sample is fixed to the support members, and the refractory test can then be carried out. During the refractory test, the combustion chamber of the furnace body can accommodate the flame burning within it, while the exhaust pipe can discharge the flue gas generated by the flame combustion from the combustion chamber. After the test sample on the refractory testing frame has completed the refractory test, the refractory testing frame can be transferred away from the support members. This utility model of a refractory testing furnace facilitates the fixing or detachment of the refractory testing frame. Attached Figure Description
